marshal hasn't changed in many years:

$ python1.5
 >>> x = 1, 2.0, "three", [4, 5, 6, "seven"], {8: 9}, None
 >>> import marshal
 >>> marshal.dump(x, open("x.dat", "w"))
 >>>

$ python2.5
 >>> import marshal
 >>> marshal.load(open("x.dat"))
(1, 2.0, 'three', [4, 5, 6, 'seven'], {8: 9}, None)

which is a good thing, because there are external non-Python tools that 
generate marshalled data streams.

maybe you were thinking about marshalled code objects?
